My P.W has consistently averaged 15 mpgs a week running 87 no eth. all summer.
After switching to 87 w/10% eth ( cause it's .40/gal cheaper) it dropped to 14.5 mpgs.
Still not terrible for a big truck with a big motor and 35" mud terrain tires.
Now that cold weather has set in I'm only getting about 13 mpgs on average.
Combination of winter blended fuel and longer warm up times I suspect.
